    • getNodeMetaData

      default <T> T getNodeMetaData(Object key)
      Gets the node metadata.
      Parameters:
      key - the metadata key
      Returns:
      the node metadata value for this key

    • getNodeMetaData

      default <T> T getNodeMetaData(Object key, Function<?,? extends T> valFn)
      Gets the node metadata.
      Parameters:
      key - the metadata key
      valFn - the metadata value supplier
      Returns:
      the node metadata value for this key

    • copyNodeMetaData

      default void copyNodeMetaData(NodeMetaDataHandler other)
      Copies all node metadata from the other node to this one
      Parameters:
      other - the other node

    • setNodeMetaData

      default void setNodeMetaData(Object key, Object value)
      Sets the node metadata.
      Parameters:
      key - the metadata key
      value - the metadata value
      Throws:
      GroovyBugError - if key is null or there is already meta data under that key

    • putNodeMetaData

      default Object putNodeMetaData(Object key, Object value)
      Sets the node metadata but allows overwriting values.
      Parameters:
      key - the metadata key
      value - the metadata value
      Returns:
      the old node metadata value for this key
      Throws:
      GroovyBugError - if key is null

    • removeNodeMetaData

      default void removeNodeMetaData(Object key)
      Removes a node metadata entry.
      Parameters:
      key - the metadata key
      Throws:
      GroovyBugError - if the key is null

    • getNodeMetaData

      default Map<?,?> getNodeMetaData()
      Returns an unmodifiable view of the current node metadata.
      Returns:
      the node metadata. Always not null.
